Boeing plans to celebrate the certification of its 787 Dreamliner on Friday.
That will pave the way for Boeing to deliver its first 787 to launch customer All Nippon Airways in September.
It’s a big month for Boeing. The company received certifications from the U.S. and Europe for its 747-8 freighter, two of the final steps before the first plane is to be delivered to Cargolux next month.
Delays on the 787 have led to significant build-up of 787 inventory — a total of $16.2 billion worth, according to Bloomberg News. Boeing has unfinished jets scattered around its Everett, Wash., plant and in a facility in San Antonio.
Boeing is more than three years behind schedule on the 787 and two years late on the 747-8F.
The company has orders for 827 787s.
